AOFS defines the electrical and power control architecture to safely operate pumps, valves, and irrigation loads under any power source. It is designed to ensure fail-safe operation, energy efficiency, and compliance with AOFS standards, independent of whether the farm uses grid, generator, or solar power.

• AOFS is power-source agnostic: it works with grid, generator, solar, or hybrid systems.
• Controllers must enforce fail-safe operation for irrigation and actuation regardless of the power source.
• Systems must support safe shutdowns in case of power anomalies or failures.
• AOFS may track energy consumption of pumps and actuators to support optional logging, reporting, and operator awareness.
  • *Recommended for off-grid or weak-grid farms, but not required for farms with stable grid power. ===== 2. Optional Solar Integration ===== AOFS supports optional solar monitoring for farms that want to optimize energy usage: * Level 1 – Minimal Monitoring (Recommended for off-grid / weak-grid farms) * Field Controllers may monitor battery voltage and current. * Supports reliable irrigation operation when solar/battery power is used. * Fully optional for farms with stable grid or generator power. * Level 2 – Integrated Monitoring (Optional Advanced Module) * Controllers can read solar generation metrics from panels/inverters via standard protocols (e.g., Modbus, MQTT, RS485). * Enables dynamic irrigation scheduling based on energy availability. * Supports advanced PUE analytics and reporting. * Completely optional — AOFS compliance does not depend on it. ===== 3. Optional Energy-Aware Operation ===== * AOFS controllers may measure power consumption of pumps, valves, and other actuators while running. * Controllers may estimate battery drain or energy availability for upcoming scheduled irrigation events. * AOFS supports event prioritization: * Each scheduled irrigation or actuator event can be assigned an urgency or importance level by operators. * If insufficient energy is available: * Low-priority events can be delayed or skipped. * High-priority events are executed as soon as sufficient energy is available. * Optional alerts notify operators of skipped or delayed events. * All energy measurements, prioritization decisions, and resulting operational logs may be recorded for later analysis: * Enables visualization of energy usage and event execution history. * Helps operators determine if additional batteries, solar panels, or load rescheduling are needed. ===== 4. Implementation Guidelines ===== * AOFS compliance does not require any specific power source, monitoring, or energy-aware operation. * Optional monitoring modules should follow AOFS data logging and offline-first principles. * All controllers and modules, regardless of power source, must enforce local fail-safes** for pumps, valves, and critical irrigation operations.
